2006 wrangler overheating

so im hoping someone can help me...I took my jeep mudding, after the night was over i noticed my gauge says that my engine was overheating...I thought it might have been a coolant leak but couldnt find one, so i drained and flushed the radiator and put new coolant in it. that didnt work so then i changed out the thermostat and when that didnt work i cleaned all the mud out of the radiator and changed the air filter and it still overheats...I had a buddy of mine check out the water pump and he said its working fine so the only other think I could think of is a gasket...Does anybody have any ideas?

Don't know anything about 06's, but did you check your fan clutch?

Common JEEP Problem, even in the newer models... So, depending if you have 6 or 4 cyls, I should be able to help... If its a 4.0L, you need to pull the Thermostat/Intake off the front of the Motor... Then you need to Grind out the back inside of the cover, as it is not really big enough to handle over exertion on the trail... YOU NEED TO BE VERY CARFUL NOT TO TAKE TOO MUCH OUT OR YOU RISK CAUSING A BLOW OUT IF THE INNER WALL IS TOO THIN... This allows for more coolant flow all the time... You may also purchase a Thermostat that will open at cooler Temps to allow flow age more rapidly... Feel free to let me know if you have any questions... Also, use caution putting it back on and torqing it too tight, its Aluminum and will crack easily... Good Luck!

I forgot to ask if you opened the peacock valve on the bottom of your radiator to make sure it's not plugged up... If its not, look very closely around the head for leakage and check to see if there is any water in your oil... A warped head will cause constant overheating...
